血液应急保障是灾后安全救援的重要环节。为既有效满足需求,又避免盲目、过量的采血、调血增大血液过期报废压力甚至血荒的发生,保障灾后安全救援顺利进行,针对血液的易腐特性,提出血液应急调度的特点,并建立在物联网技术支持下的多时段、多类型血制品、多种运输方式的优化调度模型,通过合理调用库存血,组织自采血、外调血,并确定相应的数量以满足用血需求,实现血液应急保障系统响应时间和调度总成本最小化目标。采用ILOG CPLEX软件对模型进行求解,结合汶川特大地震的实际案例,进行数值仿真与结果分析,并给出在不同中断情景下的调度策略,表明通过建立双向互调的血液供应网络,并采用调度优化方法能够以更短的时间满足用血需求,同时减小调配成本和血液报废压力,能更好地应对灾后救援中出现的供应中断情况。 相似文献

The scrap vehicle recycling program was formally initiated in 1995 when the illegal dumping issues of scrap tires and cars turn out to be intolerable in the society of Taiwan. The inherent complexity of such a recycling program, however, by integrating many public and private sectors that functions as a whole from the collection, storage, transport, treatment, and the disposal of scrape vehicles, makes the entire managerial efficiency hard to be maintained. Therefore, the state-of-the-art information technology via the use of the Internet platform becomes an indispensable tool to present a good communication mechanism, to provide the essential information sharing between all users and agencies, and to end up with improving the overall managerial efficiency. The idea using advanced web database along with geographical information system to help general public to dump their scrap vehicles smoothly and to make governmental agency control the disposal procedure easily could be one of the best solutions from the long-term environmental management perspective. This paper, representing contemporary progress of environmental management skill performed by the Foundation for Reduction, Reuse and Recovery, sponsored by the Environmental Protection Administration (EPA) in Taiwan, is designed to illustrate how to build up such a system, as named by the Scrap Vehicles Recycling Program Information System (SVRPIMS) in order to meet the requirement from both supply and demand sides of scrap vehicles disposal. Experience gained in this study indicates that the SVRPIMS successfully integrates the Coldfusion® and Mapguide® software engineering technologies on the World Wide Web (WWW) platform. After actual implementation in 1999, it proved that communication between users and agencies at various levels in the recycling program became much easier through instant information retrieval and analysis via such a system. Besides, SVRPIMS also provides two decision-support functionalities to assist in automatic search for the most appropriate dumping site for the users and to perform possible trading of spare parts for the recyclers through a logistic optimization analysis. 相似文献

苏州旅游强市与旅游要素建设--从吃、住、行三要素说起 总被引:1,自引:0,他引:1
苏州要从旅游大市提升到旅游强市,必须强化旅游吃、住、行三要素建设。苏邦菜应借鉴成功经验,改良传统名菜,重建“吃在苏州”的格局。饭店既要满足基本接待需求,更要强化会议、商务功能,加快科技化、信息化、网络化建设,健全休闲娱乐功能。以提高苏州旅游接待业的总体水平和整体吸引力。为打开旅游交通这一瓶颈,应增加营运车辆,在线路安排和旅游集散中心建设上精心策划,调动民间资本参与旅游交通建设。 相似文献
